MULTIPLE PRESS-VULCANIZER.

SPECIFICATION formingpart of Letters Patent No. 652,813, dated July e, 190e. Application inea March 29, 1900. serial No. 10,021. (No mada.)

To ctZZ whom it may concern:

Be it known that I, FRANK A'. SEIBERLING, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Multiple Press-Vulcanizers, of which the following is-a specification.

My invention has relation to improvements in ,vulcanizing-presses for'rubber tires and other articles, and it especially relates to that class'of presses in which a number of hori' zout-al hollow circular cases adapted to be heated by steam are arranged in a vertical series and adapted to be moved vertically, to separate, to receive tire-holding molds, and to be drawn together to compress and heat said molds for the process of vulcanization.

The object of my invention isA to provide improvements in devices for elevating and delivering to the press the molds holding the green tires and for removing them when the vulcanization is completed.

To the aforesaid object my invention con; sists in the peculiar and novel construction, arrangement, and combination of parts here-l inafter described and then specifically pointed out in the claims, reference being had to the 'Y ccompanying drawings, forming a part of this specicationg v Inthe accompanying drawings,`in which similar reference-numerals indicate like parts in the different views, Figure 1 is an elevation; Fig. 2, an elevation looking'from the left of Fig. 1, and Fig. 3 a plan;

Referring to the drawings, 1 is the cylinder of an upwardly single-acting hydraulic press, in which slides a plunger 2 and controlled by the inlet and outlet of the water through the opening 3. The cylinder is supported on a foundation 4 and has at each side brackets 5,' in which are securely attached rods 6, that extend above the cylinder` and bear a head 7, retained by nuts 8. Fitted to slide on the rods 6 area series of hollow circular cases 9, having side guildes 10 to t the. rods and for another purpose to'be stated. These guides consist of projecting semicircular forked lugs to partially in'close the rods, but less in height than the cases 9.

Attached to the rods 6 at determined intervals are secured, by set-screws or other means,

a series of collars 11, arranged to be severally engaged by the guides 10 on the case immediately above them and serve to arrest the descent of each case beyond a determined distance, so that when the plunger 2 has completed its downward stroke the cases'will occupy the position shown in Figs. 1 and 2. The cases 9 are arranged to be heated by live steam by a pipe 12 and brauch pipes 13, con- .nected with said pipe and the several cases, `the elbows permitting enough free movement for thatpurpose. Adjacent to but lower than the cylinder 1 is a smaller hydraulic cylinder 14, sin gle-acting upward, controlled by a valve 15, governed by a handle 16. In this cylinder is a plunger 17, bearing a head 18, 'from the corners of which arise parallel rods 19, two

yof which slide in offset-guides 20, fastened to the head 7, and thus secure accurate movement of the cases. are a series of like horizontal platformsV 21, double the number of the spaces between the cases 9 and arranged at regular intervals. At the front of the cylinder 1 is a vertical revo- 'luble shaft 22, bearing at intervals opposite ltervals similar hooded sheaves 31, located between the bifurcated ends of swinging horiyzontal arms 32, freely mounted thereon.

In the free ends of the arms 32 are like hooded sheaves 33. Passing around the pulleys or sheaves 23 are heavy cords or wires34, bear- 'ing at each end a hook. The molds 36'are of a common pattern, each consisting of two annular. castings arranged to registerand having grooves to form the tire; but each lower case is provided at each side with a perforated lu g 37, adapted to be engaged by the hooks 35.

- In operation molds with prepared tires inclosed are placed on the Working table 38 and: pushed onto alternate platforms 21 as they Attached to the rods 19 IOO are successively brought even with it by the plunger' 17 until each alternate platform bears onem old. These platforms are then adjusted vertically by the plunger 17 until each mold is brought opposite a space between the eases 9. The hooks 35 on the ends of the ropes 34, passing around the sheaves 29, are inserted in the holes in the lugs 37 nearest the press and the hand-wheel 27 turned until the molds are drawn between the cases 9. The cases 9 being heated by live steam by the pipes hereinbefore mentioned, the plunger 2 is forced upward, compressing the molds between the heated cases during the time requisite for the vulcanization of the tires. During this time another set of molds with tires inclosed is placed on alternate platforms 2l. When the time for vulcanization has elapsed, the plunger 2 is lowered, and the hooks 35 on the opposite ends of the ropes inserted in the lugs 37 on the side next to the platforms 21 of the molds in the press, and these molds with the cured ties drawn upon the empty platforms 2l. The position of these platforms is slightly changed, bringing the molds with the green tires in alinement with the spaces between the cases 9, and the process repeated. The platforms are then graduallylowered and one by one the molds containing the cured tires are drawn out upon the working table and their places are filled by molds containing green tires and the platforms raised until the platforms are brought opposite the spaces between the cases 9, and the process repeated. In placing and removing the molds from the platforms 21 the arms 32 are rocked out of the way, as indicated in dotted lines in Figs. l and 3.

I am aware that a number of vulcanizers held down by a head retained by side bolts and pressed upward by a hydraulic press is of itself not new, and such I do not broadly claim; but

What I claim, and desire to secure by Letters Patent, is-

1. The combination with a vertically-acting vulcanizer and means for operating it, a vcrtically-moving plunger-actuated platform in juxtaposition therewith with independent means for operating'it, of means for transferring molds from said platform to said vulcanizer and removing them therefrom.

2. The combination with a vertically-actin g vulcanizer and means for operating it, a vertically-moving plunger-actuated platform in juxtaposition therewith with independent means for operating it, of means for supplying said vnlcanizer with a complement of molds at one operation.

3. The combination with a vertically-acting vulcanizer and means for operating it, a vertically-moving plunger-actuated platform in juxtaposition therewith with independent means for operating it, of means for simultaneously supplying said vulcanizer with a complement of molds at one operation and removing all of said molds simultaneously at a succeeding operation.

4. The combination with a vertically-acting vulcanizer, mechanism arranged to lill said vulcanizer with molds at one operation and empty it at a next succeeding operation, of a plunger-actuated platform arranged to operate in conjunction therewith provided with compartments for holding the molds containing the unvulcanized articles to be supplied to said vulcanizer and receive a like number of molds with vulcanized products from said vulcanizer.

5. In a vulcanizer of the class specified the Acombination with a hydraulic cylinder and its plunger, guide-rods connected with said cylinder and a head attached to and supported by said guide-rods, of hollow cases arranged to be heated by live steam having guides to run on said rods, and collars sccured'to said guide-rods to limit the descent of said several cases respectively, substantially as shown'and described.
